JEAN SOHAFHAUS, OF NEW YORK, N. Y.

FLOATING COOLER.

SPECIFICATION forming part of Letters Patent No. 238,809, dated March I5, 1881.

Application filed J january 20, 1881.

To all whom it may concern Be it known that I, JEAN SCHAFHAUS, a

i citizen ofthe United States, residing in New York, in the State of New York,have1nveuted a new and useful Improvement in Floating Coolers, of which the following is a specification.

The nature of my invention consists in a cooler to be inserted o r placed in a beer-vat for cooling the beer during the process of undergoin g fermentation, capable of being easily moved about and raised or lowered in the tluid in the vat as may be required.

The accompanying drawing represents a section ot' my improved cooler placed in a vat, where A represents the vat, and B the cooler. This cooler consists of a lower cylindrical chamber, a, and an upper chamber, b, considerably enlarged, capable ot' acting as a ioa-t to support the cooler in the liquid. Through the center a large open space, d, is made t0 allow the liquid to pass and come in contact with the cooling-Huid placed in the cooler 011 the interior and exterior surfaces of said cooler.

O isapipe to supply the cooling-liquid to the cooler. This pipe is carried nearly to the bottom ofthe cooler. In the top of the enlarged part or of the oating part b a pipe, n, is screwed, capable of being made higher orlower, as maybe desired, and for the purpose hereinafter mentioned. To this the pi pea' is attached (No model.)

to carry oftl the surplus and heated fluid from the cooler. By this arrangement of screwing the pipe n farther inward or ot' bringing the end nearer to the top of the chamber b, the air in the upper part. ot' said chamber can be increased or diminished, increasingI or diminishing thereby the buoyancy of the tloat, and. causing the same to sink more or less in the uid in the Vat.

m is a small cock in the top of the cooler to allow the air to escape, it' desired.

To the ooupling ofthe pipe ca siphon may be attached for drawing the fluid from the cooler whenever' it is desired to lift the same out of the vat.

This tloat-ing cooler can easily be moved about in the vat, raised or lowered as may be desired, and removed from the uid the exact moment the required degree of fermentation ofthe liquid is obtained.

What l claim as my invention, and desire to secure by Letters Patent, is-

A cooler consisting of a concentric lower chamber, a, and an enlarged upper chamber, b, iu combination with a pipe, a, capable of being regulated substantially in the manner and for the purpose herein described.
